CAR-WHEEL.

Specification of Letters Patent.

Patented Dec. 11, 1906.

Application filed September 15,1905. Serial No. 278,578.

To ctZZ whom it may concern:

Be it known that I, FRANCIS E. HoLLmAY, a citizen of the United States, residing at Jellico, in the county of Whitley, State of Tennessee, have invented certain new and useful Improvements in Car-Wheels and I do hereby declare the followin to be a full, clear,

and exact description 0 the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to wheels, and more particularly to car-wheels, and has for its object to provide a self-oiling car-wheel which will include a novel arrangement of parts and which may be placed upon a spindle and re moved therefrom without loss of oil.

Another object is to provide a wheel of this kind which may be held in position upon a car by means of a cotter-pin and without the use of retaining-caps, &c.

Another object is to provide a wheel embodying the above features which may be manufactured at a low figure.

Other objects and advantages will be apparent from the following specification, which describes an embodiment of the pres ent invention.

In the drawings forming a portion. of this specification, and in which like numerals of reference indicate similar parts in the sev eral views, Figure l is a side elevation of the present wheel. Fig. 2 is a section on line 2 2 of Fig. 1, the wheel being engaged with a spindle. Fig. 3 is a View of the wheel with the face-plate removed. Fig' 4 is a view of a portion of a car provided with the present wheel, the latter being in position for removal to prevent loss of oil when removed and being partly in section.

Referring now to the drawings, the present invention comprises a hub 5 and a tread 6, which are connected by spokes 7 of the usual type and a transversely-enlarged spoke 8. The hub 5 is hollow and is open at one side, the opposite side wall of the hub having an opening 9 therethrough which receives one end of a skein 10, the opposite end of the skein projecting beyond the open side of the hub, and this skein lies in spaced relation to the circular wall 11 of the hub and is held in position by frictional engagement of the surrounding portions. The enlarged spoke 8 is also hollow and is open at the same side as that at which the hub 5 is open, the interior of the hub being separated from that of the spoke by a web 12, which is a continuation of the Wall 11. The spoke has end walls 13, which are curved and which diverge outwardly, so that the chamber 14 within the spoke tapers toward the hub, and formed through the web 12 adjacent to each of the walls 13 there is a transverse slot 15, these slots permitting of the passage of oil from the chamber 14 to the chamber 16 within the hub.

A face-plate 17 is provided and includes a circular portion 18, adapted to cover the open side of a hub, and a wing 19, adapted to cover the open side of a spoke, and this face-plate is secured in position to close the chambers 14 and 16 by means of attaching-screws 20, the circular portion 18 of the face-plate having an opening 21 therein which receives the skein 10. It will thus be apparent that the face-plate may be removed to permit of cleaning the chambers.

Oil-passages 21 are formed through the skein at opposite sides thereof, and these passages lie in a plane between the slots 15, so that oil is prevented from passing directly from these slots to the interior of the skein. In use oil is introduced into the chamber 14 through an opening 22, formed in the faceplate 17 and which is provided with a suitable removable closure 23, and from the chamber 14 the oil passes into the chamber 16 and thence to the interior of the skein 10, which is of course'disposed upon a spindle 24, the latter having a cotter-pin 25 engaged therethrough to hold the wheel in position. It will thus be apparent that the wheel may be removed from the spindle and that if the spoke 8 be kept at the lower portion of the wheel the oil will be retained therein and will thus be saved until the wheel is again placed upon the spindle.

In Fig. 4 there is shown a modified form of the invention, in which the wheel is cast integral, the skein 10 being held in position frictionally, as in the first-described form.

What is claimed is A self-oiling wheel for cars comprising a hub, a skein engaged in the hub, said hub having a chamber therewithin surrounding the skein, a tread surrounding the hub, connecting-spokes between the hub and tread, one of said spokes being enlarged transversely and having a chamber therewithin tapered toward the hub, and a separating- I In testimony whereof I affix my signature Web between the chamber of the hub and in presence of two witnesses. that of the spoke, said separating-web hev- FRANCIS E HOLLIDAY ing a, slot formed therethrough, said skein having spaced 0 enings therein communieating with the chamber of the hub and the interior of the skein.
